Auto-scaling
Automatically giving a system more or less computing power as usage rises and falls
What's it for?
Lets a service add or remove computing power automatically as demand changes.
For example…
When a product launch brings a sudden rush of visitors, the website automatically adds more computing power and removes it again when traffic falls
A ticketing website automatically adds web servers when a concert goes on sale and removes them after demand falls
Think of it like…
A supermarket automatically opening extra tills when queues grow and closing them again when things quieten down
